Sequence of Events Question

Put a smooth, clean, iron frying pan on the fire to heat; meanwhile, beat four eggs very light, the whites to a stiff froth and the yolks to a thick batter. Add to the yolks four tablespoonfuls of milk, pepper and salt; and, lastly, stir in the whites lightly. Put a piece of butter nearly half the size of an egg into the heated pan; turn it so that it will moisten the entire bottom, taking care that it does not scorch. Just as it begins to boil, pour in the eggs. Hold the frying pan handle in your left hand, and, as the eggs whiten, carefully, with a spoon, draw up lightly from the bottom, letting the raw part run out on the pan, till all be equally cooked; shake with your left hand, till the omelet be free from the pan, then turn with a spoon one half of the omelet over the other; let it remain a moment, but continue shaking, lest it adhere; toss to a warm platter held in the right hand, or lift with a flat, broad shovel; the omelet will be firm around the edge, but creamy and light inside.
